The major components of the WebLogic JMS Server architecture, as illustrated in the figure below.

*

(A) JMS servers that can host a defined set of modules and any associated persistent storage that reside on a WebLogic Server instance.

*

(B) JMS modules contains configuration resources (such as queues, topics, and connections factories) and are defined by XML documents that conform to the weblogic-jmsmd.xsd schema.

*

Client JMS applications that either produce messages to destinations or consume messages from destinations.

*

JNDI (Java Naming and Directory Interface), which provides a resource lookup facility. JMS resources such as connection factories and destinations are configured with a JNDI name. The runtime implementations of these resources are then bound into JNDI using the given names.

*

(E) WebLogic persistent storage (file store or JDBC-accessible) for storing persistent message data.

The following figure illustrates the WebLogic JMS architecture.

Correct Answer: CEF

Note:

*

Two or more Managed Servers can be configured as a WebLogic Server cluster to increase application scalability and availability. In a WebLogic Server cluster, most resources and services are deployed identically to each Managed Server (as opposed to a single Managed Server), enabling failover and load balancing. A single domain can contain multiple WebLogic Server clusters, as well as multiple Managed

Servers that are not configured as clusters. The key difference between clustered and non-clustered Managed Servers is support for failover and load balancing. These features are available only in a cluster of Managed Servers.

*

A WebLogic Server cluster provides these benefits: Scalability The capacity of an application deployed on a WebLogic Server cluster can be increased dynamically to meet demand. You can add server instances to a cluster without interruption of service--the application continues to run without impact to clients and end users. High-Availability In a WebLogic Server cluster, application processing can continue when a server instance fails. You "cluster" application components by deploying them on multiple server instances in the cluster--so, if a server instance on which a component is running fails, another server instance on which that component is deployed can continue application processing.

Correct Answer: ABDE

The following principles encourage RESTful applications to be simple, lightweight, and fast:

*

Resource identification through URI

*

Uniform interface: Resources are manipulated using a fixed set of four create, read, update, delete operations: PUT, GET, POST, and DELETE. PUT creates a new resource, which can be then deleted by using DELETE. GET retrieves the current state of a resource in some representation. POST transfers a new state onto a resource. See Responding to HTTP Methods and Requests for more information.

*

Self-descriptive messages

*

Stateful interactions through hyperlinks

Correct Answer: BE

E: Oracle Enterprise Pack for Eclipse 12c (12.1.1.2.1) Eclipse Based Enterprise Application Development Oracle Enterprise Pack for Eclipse (OEPE) 12.1.1.2.1 for Eclipse Juno provides tools that make it easier to develop applications utilizing specific Oracle Fusion Middleware technologies and Oracle Database.

Note:

* Support for IDE's. WebLogic already supported JDeveloper 11.1.1.5, but will come out with the 11.1.1.6 later on. Also suported are Eclipse and NetBeans 7.1 IDE. The JDeveloper 11.1.1.6 and IntelliJIdea IDE will be supported in a later timeframe.

Correct Answer: C

. The JMS SAF Client feature extends the JMS store-and-forward service introduced in WebLogic Server

9.0 to standalone JMS clients. Now JMS clients can reliably send messages to server-side JMS destinations, even when the client cannot reach a destination (for example, due to a temporary network connection failure). While disconnected from the server, messages sent by a JMS SAF client are stored locally on the client file system and are forwarded to server-side JMS destinations when the client reconnects. See Reliably Sending Messages Using the JMS SAF Client.

Correct Answer: AC

Note:

*

Apache Maven is a software tool for building and managing Java-based projects. WebLogic Server provides support for Maven through the provisioning of plug-ins that enable you to perform various operations on WebLogic Server from within a Maven environment.

*

Continuous Integration is a software engineering practice which attempts to improve quality and reduce time to deliver software by applying small, frequent quality control efforts. It is characterized by these key practices: Use of a version control system All developers commit to the `HEAD' (main code line) every day The product is built on every commit The build must be automated and fast Automated deployment to a production-like environment Automated testing Results of all builds are published (so everyone can see who broke the build) Deliverables are easily available (for developers, testers, other stakeholders)

Correct Answer: CE

C:

*

A WebLogic Messaging Bridge communicates with the configured source and target bridge destinations. For each mapping of a source destination to a target destination, you must configure a messaging bridge instance. Each messaging bridge instance defines the source and target destination for the mapping, a message filtering selector, a QOS, transaction semantics, and various reconnection parameters.

Note:

*

In your JMS Foreign Server configuration:

/ Specify oracle.jms.AQjmsInitialContextFactory as the JNDI Initial Context Factory. / Configure the JDBC

data sources needed for your application environment.

Correct Answer: B

fair-share-request-class--Specifies the average thread-use time required to process requests. The default fair share value is 50.

For example, assume that WebLogic Server is running two modules. The Work Manager for ModuleA specifies a fair-share-request-class of 80 and the Work Manager for ModuleB specifies a fair-sharerequest-class of 20. During a period of sufficient demand, with a steady stream of requests for each module such that the number requests exceed the number of threads, WebLogic Server will allocate 80% and 20% of the thread-usage time to ModuleA and ModuleB, respectively.

* Example:

lowpriority_workmanager low_priority 10

highpriority_workmanager high_priority 100

Note:

* A request class expresses a scheduling guideline that WebLogic Server uses to allocate threads to requests. Request classes help ensure that high priority work is scheduled before less important work, even if the high priority work is submitted after the lower priority work.

Incorrect:

Not C: response-time-request-class--Specifies a response time goal in milliseconds. Response time goals

are not applied to individual requests. Instead, WebLogic Server computes a tolerable waiting time for

requests with that class by subtracting the observed average thread use time from the response time goal,

and schedules requests so that the average wait for requests with the class is proportional to its tolerable

waiting time.

Not A, D: Not related to thread constraints.

For example, assume that WebLogic Server is running two modules. The Work Manager for ModuleA

specifies a fair-share-request-class of 80 and the Work Manager for ModuleB specifies a fair-sharerequest-class of 20.

Correct Answer: A

A Node Manager process is not associated with a specific WebLogic domain but with a machine. You can use the same Node Manager process to control server instances in any WebLogic Server domain, as long as the server instances reside on the same machine as the Node Manager process. Node Manager must run on each computer that hosts WebLogic Server instances--whether Administration Server or Managed Server--that you want to control with Node Manager.
